(50G) Question, has anyone programmed gauss's...
has anyone wrote program to solve gauss's shoelace formula with a 50G?

Thanks for reply, whats GSLIST? the \GSLIST is erroring this, but nice code. i get 'GSLIST/2.' edit: GOTIT! the statistics EList function... this is good thanks Thanks ~~~~8< Art >8~~~~ PS: Please post more 50G stuff :)

RE: 50G Question, has anyone programmed gauss's...
This program is for the HP42S:
Code: 00 { 39Byte Prgm } Example: Consider the polygon defined by the points (3,4), (5,11), (12,8), (9,5), and (5,6). 1 ENTER NEWMAT x: [ 1×1 Matrix ] 0 ENTER COMPLEX + x: [ 1×1 Cpx Matrix ] EDIT GROW 3 ENTER 4 COMPLEX → 5 ENTER 11 COMPLEX → 12 ENTER 8 COMPLEX → 9 ENTER 5 COMPLEX → 5 ENTER 6 COMPLEX EXIT x: [ 5×1 Cpx Matrix ] XEQ "AREA" y: [ 5×1 Cpx Matrix ] x: 30

(06042014 07:03 AM)Thomas Klemm Wrote: This program is for the HP42S: This is great and provided another great example, I have difficulty comparing the code or even seeing how it works because I don't have a 42S. I would have difficulty porting 42S code to my 50G, and I do wish 50G had "LBL" and "GOTO" like my old 41 did. I added a front end to the original 50G code above, so I can post it if anyone is interested? still a 50G work in progress but I have it asking for input and it stops and calculates if 0, 0 is entered.

RE: 50G Question, has anyone programmed gauss's...
OK so after 30 seconds no one was interested but I'm going to post this 50G code anyhow in hopes someone will look at it and give some pointers...
Code:
This just asks for input till 0,0 is input then calculates the area. Next (someday) I plan to sum the end areas into a volume using average end area * length. Thanks ~~~~8< Art >8~~~~ PS: Please post more 50G stuff :)

Here is a version for HP28S/C and any other old style RPL :
